Applicatimn'.rune 9, 1931. seriarN'o. 543,166 v2-(nannaL (c1. la7- 13) I This invention relates to a hydrant for use during all seasons of the year without danger of freezing and without producing' an excessive v waste of water;

In cemeteries, public parks, and other localities it is the practice to provide waterhydrants forV drinkingr and other purposes. Inrorder to prevent freezing it has been found desirable to use hydrants which will drain into thesoil when ated in the same manner at all times of the year with the result that, during warm weather when the demand for water isg1eatest,-therehas'been a vast waste due to the fact that every time the hydrant has been closedithas also been drained. As no need of draining isprpesent during warm weather, this waste has beenV entirely unnecessary. It has also been objectionable because the roots of nearby vegetation have sought the moisture suppliedby drainage and have quickly accumulated in amat around the'drain portion of the hydrant,' some of the roots Vfrequently working into the drain'opening or b leeder and choking it, thereby preventing proper functioning ofY the hydrant. n Y 4 l It is an object of the present invention to provide ahydrant whichV is simple and efficient in construction and can be converted quickly from a warm-weather, non-draining fixture `into a selfdraining, non-freezing device for winter use.' Another object is toprovide a hydrant the drain or bleeder opening of which is entirely closed during the plant growing season so that it will not attractplant life by underground waste water nor allow anynearby 'root growths `to enter and choke the opening. f

A still further object is'to provide a hydrant in which the water is ,kept` under pressure from the main at all times so as thus to be maintained fresh and sanitaryvinstead of becoming stale as when cut-off from the main and exposed to atmospheric action betweenl periods of use.v

Another object is to provide a hydrant which can be used as a bubble or drinkingfountain and still have all of theadvantagesV enumerated. -With the foregoing and other objects inview which will appear as Vthe Ydescription proceeds, the invention resides in the combination and ai'- rangement of parts and in the details of con- 'struction hereinafter described andclaimed, it beingunderstood that changes inthe precise embodiment of the invention herein disclosedmay be made within the scope of what is claimed Without departing from the spirit rof the invention.V

the valve is closed. These hydrantsv have oper- In the accompanying drawings the preferred formsv of the invention have been shown.

In said drawings: Y l Y Figure 1 is a view partly in side elevation and partly in sectionof a hydrant having the present improvements, parts being broken away andthe valve shown in open, non-draining position. A

Figure 2 is a similar -viewshowing the valve closed and in draining position for winter use.

Figure 3 is a section on line '3-3, Figure l, looking downwardly. Y

Figure 4 is a vertical section through a portion Y of the hydrant showing the outlet valve fastenedl in open position.

Figure 5'is a verticalsection through a modified structure including a bubble fountain, parts being broken away. k Y

Figure 6 is a section on line 6 6, Figure 5, the faucet being shown in plan.

Referring to the figures by characters of reference 1 designates `opposed foot members or castingsv having contacting inturned lower ends 2 while their upper ends are recessed at 3 to embrace and clamp upon the lower end of a casing pipe' 4, there being ltransverse bolts 5 inthe foot members for drawing them together.

The upper end of the casing pipe is housed `in a sleeve 6 carrying a screwf adapted to bev inserted into any one of several holes 8 formed mately Sleeve 6 has an interior flange 9 which bears onv the upper end of pipe ltand extending downwardly into the sleeve from its upper end is a slot 10.

Seated in the sleeve 6 and bearing downward- Y 1y on ange 9 is a control faucet 11 the nozzle 12 of which extends through slot 10. The valve '13 of the faucet is preferably of that type held normally in closed position on its seatY 14 by a spring 15. The stem 16 ofthe valve extends through the top of the faucet and is turned'by Vmeans of a handlel'. Cooperating cam faces,

indicated generally at 18, act to unseat the valve against the action Vof spring 15 when the stern is rotated in one direction. 'When the handle is released the springv will tend to close the valve.

This is an'old construction and, Yintself, forms no part of the present invention.

, Secured to the'facuet 11 so as to rotate therewith is a riser pipe 19 which extends downwardly within the casing pipe 4 and into the space between the foot members 1.l Here itis secured in a socket' member 20 carried by the upper end of a main valve in the form of a tapered plug During warm weather when there is no danger of freezing and when there is a frequent demand for water, the screw '7 is removed and the nozzle 12 of the controlling faucet is used as a handle for turning the faucet, the sleeve 6 and the riseV This will bring main valve pipe 19 through 90. 20 to the position shown in Figure 1 so that water from the main will be supplied constantly under pressure to the faucet where it is normally cut oi from the atmosphere. By reinserting screw 7 into Vthe adjacent aperture 8 the parts will be held in these positions. Thus by opening -the valve in the faucet the water can be .drawn at will and at no time will there be Yany drainage into the soil at 24 tending to promote root growth.

During the winter season when the water is used infrequently the screw 7 is removed and the faucet nozzle is swung through 90 to close the main valve and uncover the drain or bleeder openings. Thus water trapped in the riser pipe will quickly drain into the soil and as there is no plant development at that time, the moisture delivered to the soil will not tend to promote root growth.

Whenever water is desired the faucet can be swung back to its original position so as to open the main valve. The main valve can be secured in closed position by inserting screw 7 into one of the holes 8 while the main valve is closed.

The faucet valve i Till close automatically under the action of its spring but can be held open' if desired by means of a screw 25 adapted to be forced under a shoulder 26 movable with the handle 17. See Figure 4.

In the structure shown in Figures 1 and 2 the sleeve '6 is provided with a dome-like cap k2'? the shape of which will prevent objects from being wedged under theV handle 17 by unauthorized persons endeavoring to produce a continuous liow from the faucet.

A modification of the device has been illustrated in Figures 5 and 6. `1n this structure the casing pipe 28 is secured to a base 29 adapted to rest on the ground. A bowl 30 is mounted on the upper end of the pipe 28 and supported therein is a valved drinking fountain 31. A drain pipe 32 extends downwardly from the bowl.

A slot 33 in the casing pipe 28 extends partly therearound and projecting therethrough is a faucet 34 attached to a branch 35 extending from riser pipe 36. This riser pipe opens at its upper end into the fountain 31 while its lower end is connected to a main valve 37 and operates it in the same manner as hereinbefore explained.

A sleeve 38 is rotatable on the casing pipe 28 and extension 35 projects through it. This sleeve covers slot 33 and carries a screw 39 which can be inserted in either of two openings 40 in the casing pipe, thereby to hold the riser pipe and the valve 37 in either open or closed position.

, What is claimed is:

1. A hydrant including a casing pipe, foot members connected to the lower end of the pipe, a valvej casing between said members having an inlet and a drain outlet, a tubular plug valve foropening the inlet and the drain outlet separately, a riser pipe opening into and rigidly connected to the plug valve, a sleeve rotatable upon and bearing downwardly on the casing pipe, a faucet extending from the riser pipe and through the sleeve, said faucet bearing on the sleeve to support the riser pipe, the faucet constituting means for 'rotating-the sleeve and riser pipe to actuate the plug valve and open or close either the inlet or the drain outlet, a spring seated valve reciprocable in the faucet, a handle, a cam operated thereby for reciprocating said valve to unseatY it, means for engaging under the handle to hold the valve unseated, and means for holding the sleeve and faucet against rotation.

2..
